FWIW: it should go a little bit (0.1 em?) under the baseline.
If one wants to be really fancy: leave little gaps for descenders 
and diacritics below (like cedilla, comma below, ...) to go
"trough".  That may be a bit difficult though...

FWIW: for Latin/Greek/Cyrillic: a line at half x-height
above the baseline.  If all letters in that run are uppercase:
at half M-height from the baseline.

Whoever uses that?  Anyway, FWIW: At least one level of
diacritics on top of capital letters should fit under the
overline, or one must make gaps for the diacritics on top,
if the overline is just above the M-height rather than
above the Å-height (compare underline with decenders or
diacritics below in the text).
